Owners of Acer R11 and Asus Flip Chromebooks can now access the Google Play Store without having to use the beta version of Chrome OS. You can now run the stable, widely distributed Chrome OS and access the Google Play Store on your Chromebook.

The list of Android apps that can be used on a Chromebook as steadily expanded. That list can be seen on this Chrome Web Store page (note, the page only displays the apps if you are viewing it on a Chromebook).

Applications for Education
As the number of Android apps that can run on Chromebooks expands, we'll find that more students can quickly transition from using their Chromebooks at school to using the same apps on their personal devices. This could make it easier for students to continue working on a project as they can quickly transition from one device to the next.
